Logan Stephenson was just two years old when he died Monday night in his mother’s arms in their home outside Pittsburgh,Pennsylvania. Where two days ago little Logan served as the best man at mom and dad’s wedding:

(Christine Stephenson) “We’re all together and celebrating. It’s my heart. It’s my heart and my soul to be here and to do this with my family.”

Christine and Sean Stephenson were supposed to get married next year, but moved up the date when the boy’s doctor said he had just weeks to live, suffering from leukemia. They wanted Logan to see the ceremony and always be in their wedding photos.
